The paper presents a novel Three-tier Parallel Genetic Algorithm (TPGA) based on multi-core computer with Threading Building Blocks (TBB). The purpose of a new parallel function is to improve the running efficiency. TPGA is decomposed into three-tier: data coding parallelism, task processing parallelism and data decoding parallelism and it can improve the convergence rate. TBB offers a rich and complete...
The paper presents one novel algorithms: Parallel Floyd-Warshall algorithm(PF) based on multi-core computer with Threading Building Blocks (TBB). TBB offers a rich and complete approach to express parallelism in a C++ program. Serial Floyd-Warshall algorithm(SF) and PF are implemented and verified with TBB for the all-pairs shortest path problem. Experiments show that the efficiency of multi-threaded...
The paper presents two novel algorithms: Parallel Simulated Annealing algorithm with Memory function (PSAM) and adaptive PSAM based on multi-core computer with Threading Building Blocks (TBB). TBB offers a rich and complete approach to express parallelism in a C++ program. The purpose of a new memory function is not to trap into a local optimization. Sequential Simulated Annealing algorithm with Memory...
Most of the current trust models in peer-to-peer (P2P) systems are identity based, which means that in order for one peer to trust another, it needs to know the other peer's identity. Hence, there exists an inherent tradeoff between trust and anonymity. To the best of our knowledge, there is currently no P2P protocol that provides complete mutual anonymity as well as authentication and trust management...
